I charged my iPhone 4 during the night. In the morning, this is what happend: Image iPhone can’t be turned on. Charging with original charger doesn’t help. The USB cable was Apple’s and the charger wasn’t. Help please!

Hold the cicle button and power button at the same time for 20 seconds. This is a hard boot. I had the same problem it works. This happens because the phone lost all power before you began charging it. This is a good one to remember. Dancing Bear

take the phone to Apple store and get it replaced by them. Do NOT mention using 3rd party charger, they would refuse swap otherwise…

if you are from the uk you can take phone back to phone shop/network shop you bought it from. there are apple shops here too!
